Experimental evaluation of pressure drop elements and fabricated nucleation sites for stabilizing flow boiling in minichannels and microchannels
(American society of mechanical engineers (ASME), 2005-06)
The flow boiling process suffers from severe instabilities
induced due to nucleation of vapor bubbles in a minichannel or
a microchannel in a superheated liquid environment. In an
effort to improve the flow boiling ...
Single-phase liquid heat transfer in microchannels
(American society of mechanical engineers (ASME), 2005-06)
The development of advanced microchannel heat
exchangers and microfluidic devices is dependent upon the
understanding of the fundamental heat transfer processes that
occur in these systems. Several researchers have ...
Effects of repeating microstructures on pressure drop in rectangular minichannels
(American Society of Mechanical Engineers (ASME), 2005-06)
A literature review in laminar incompressible flow in
microchannels has shown both early and late transitions from
laminar to turbulent flow as well as no deviation from the
conventional flow transition of Re=2300. In ...
Single-phase liquid friction factors in microchannels
(American society of mechanical engineers (ASME), 2005-06)
The validity of friction factor theory based upon
conventional sized passages for microchannel flows is still an
active area of research. Several researchers have reported
significant deviation from predicted values, ...
Review of fabrication of nanochannels for single phase liquid flow
(American Society of Mechanical Engineers (ASME), 2005-06)
The topic of single phase liquid flow in submicron or
nanochannels is a nascent field. There have only been a couple
papers that have dealt with this area directly. The most
probable reason for this is that currently ...
Development of an experimental facility for investigating single-phase liquid flow in microchannels
(American Society of Mechanical Engineers (ASME), 2005-06)
An experimental facility is developed to investigate singlephase
liquid heat transfer and pressure drop in a variety of
microchannel geometries. The facility is capable of accurately
measuring the fluid temperatures, ...
Characterization of the effect of surface roughness and texture on fluid flow - past, present, and future
(American Society of Mechanical Engineers (ASME), 2005-06)
That surface roughness has an effect on fluid flow in
networks has been understood for well over a century. The
exact effect roughness has on fluid flow has not been
completely understood, but a working estimate has ...
High flux heat removal with microchannels - A roadmap of challenges and opportunities
(American Society of Mechanical Engineers (ASME), 2005-06)
Heat fluxes in IC chips and other electronics equipment
have reached the current limits of air cooling technology.
Some of the applications require heat fluxes well beyond the
limit of 100 W/cm2, requiring advanced ...
Numerical simulation of growth of a vapor bubble during flow boiling of water in a microchannel
(Spring-Verlag, 2005-05)
The present study is performed to numerically
analyze the growth of a vapor bubble during flow of
water through a microchannel. The complete Navier-
Stokes equations, along with continuity and energy
equations, are ...
Experimental study of heat transfer in an evaporating meniscus on a moving heated surface
(American Society of Mechanical Engineers, 2005-03)
A stable meniscus is formed by a circular nozzle dispensing water over a heated circular
face of a rotating cylindrical copper block. The nozzle is offset from the axis of rotation of
the copper block and thus a moving ...
